How does a six thermometer work?
How The Six’s Thermometer Works. When the temperature increases alcohol in the left bulb expands and pushes the mercury in the U shaped bend towards the right tube where there is vacuum bulb. The vacuum bulb’s purpose is to allow mercury to be pushed towards it when alcohol expands in the right tube.
How do you reset a maximum minimum thermometer?
Push Button – The MIN/MAX thermometer is reset by using the push button normally found in the middle of the thermometer between the two tubes. 1. After you have taken the minimum and maximum readings, simply hold in the push-button to reset the magnetic indicators for the next day’s data.
How do you use a maximum and minimum thermometer?
How to read the thermometer
- The minimum temperature is read on the left hand side – note red indicates below freezing point.
- The maximum temperature is read on the right hand side – black indicates above freezing point.
What is the use of maximum and minimum thermometer Class 7?
It helps to measure the maximum and minimum temperature in a day of a place. It is a U-shaped tube filled with alcohol and mercury. The right tube gives us the maximum temperature while the left tube gives us the minimum temperature.
How do you use 6 maximum and minimum thermometers?
Six’s Maximum and Minimum thermometer is a U shaped parallel tube made up of glass. One side registers the maximum temperature and the other side records the minimum temperature. The bend at the bottom of the thermometer contains mercury which moves up or down based on the expansion and contraction of alcohol.
Why is mercury used in a six’s thermometer?
Hint: The Six’s thermometer uses a U-shaped bent tube which uses two different fluids to measure temperature, that is mercury and alcohol. Mercury is used to record the temperature and the alcohol is to push it based on temperature.

How do you reset a clinical thermometer?
Put the thermometer stem or probe into the ice water. Make sure the sensing area is under water. Wait 30 seconds or until the reading stays steady. Adjust the thermometer so it reads 32˚F (0˚C).
What is the use of six maximum and minimum thermometer?
Six’s maximum and the minimum thermometer is mainly used for measuring the maximum and minimum temperature of the particular day. Apparatus Description: The six’s thermometer consists of a U-shaped capillary tube with the bulbs at both ends. The bend of the U shaped-tube is filled with mercury.

What are the 5 uses of thermometer?
Body temperature is measured with a medical or clinical thermometer. Laboratory thermometer is used to determine the room temperature of heated solids and liquids. Infrared thermometers can take readings from a distance. Restaurants use thermometers to monitor the temperature of the dishes for baking and cooking.
How does the 6 maximum and minimum thermometer work?
What is maximum and minimum temperature?
Temperatures vary with the time of day, which is why two terms are used to express that. Namely: Great temperature, temperature Minor, and be maximum temperature of the highest temperature recorded in the day, the minimum temperature is less temperature registered on the same day.
What are characteristics of Six’s thermometer?
A combination maximum-minimum thermometer. It has a U-shaped glass tube whose bottom half is filled with mercury. The left-hand horn is filled with alcohol, and the right-hand horn is partially filled with alcohol; the remaining portion has a gas above it.
Why is alcohol used in sixth thermometer?
Who invented the Six’s thermometer?
James SixSix’s thermometer / Inventor
It was invented by the British scientist James Six, in 1780; the same basic design remains in use. It is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.
How do you use a thermometer step by step?
How do I take a temperature?
- Clean the tip with cold water and soap, then rinse it.
- Turn the thermometer on.
- Put the tip under your tongue, towards the back of your mouth.
- Close your lips around the thermometer.
- Wait until it beeps or flashes.
- Check the temperature on the display.
Why is my digital thermometer not working?
Replace the battery
The flexible tip thermometer has a long-life battery which should last for about 2 to 3 years. If the battery is low, you can replace the battery as follows before using the thermometer: Remove the battery compartment cover. Use an insulated probe to remove the battery (e.g. a toothpick)
Why is my thermometer not working?
Try pressing it with your nail, or try to use a firm surface like a counter or tabletop to depress the button all the way. If that doesn’t work, try reseating the current battery in your thermometer. Use a coin (no other tools, they may damage the thermometer) to twist the back off counterclockwise.
How do you reset the temperature on a digital thermometer?
Reset the thermometer by pressing reset button. Place the thermometer under the tongue. Close mouth around thermometer. Leave in place until you hear the beep (usually one minute or less)
What is Max temperature?
It’s called the Planck temperature, after the German physicist Max Planck, and it equals about 100 million million million million million degrees, or 1032 Kelvin.
What is the limit of temperature?
Short answer: 142,000,000,000,000,000,000,000,000,000,000 Kelvin, give or take a few zeros. It’s easy to understand the theoretical minimum temperature: absolute zero.
What are the 7 types of thermometer?
There are different types, but not all thermometers are right for your child.
- Digital thermometers.
- Ear (or tympanic) thermometers.
- Infared thermometers.
- Strip-type thermometers.
- Mercury thermometers.
Where is a thermometer used?
Oral: For this method, the thermometer is placed under the tongue. This method is used for adults and children 4 and over who are able to hold thermometer in mouth. Rectal: For this method, the thermometer is inserted gently into the rectum. This is mostly done in babies but can used in children up to 3 years of age.
How does a maximum thermometer work?
As the temperature rises, a portion of the mercury is forced past the constriction and into the graduated section. This mercury is retained when the temperature falls and serves to indicate the highest temperature reached. Bimetallic thermometers with a circular scale are also used as maximum thermometers.
